no reverse

First and formost MERRY CHRISTMAS EVERYONE
the suburban has been running great . Last night my son went to 7/11 and when he got home he told me it had no reverse. All forward gears seem fine. Tranny is a 4L80E. Aperently this is a common problem with this tranny. HELP!!

They can go out that fast. If it did start slipping, the fluid will be a brown like color and smell as bad as it looks.

Yea mine did the same slipped a bit , then bang no reverse.. rebuild time.... make sure if you have it rebuilt change the pressure relief valve in the pump. if it sticks it can blow the insides out.
